But the dead man's family disputes the police version of the incident, saying that there was no domestic dispute and that he was shot without warning after a neighbour called the police about shouting.

The police are investigating the incident, and Beijing has called on Paris to "guarantee the safety and legal rights and interests of Chinese citizens in France".

"We want to maintain pressure and support the family to establish the truth and fight police violence," said Sacha Lin Jung of the Chinese Residents in France association, one of the protest's organisers.
